Is there a way to know the avaliable ram in a server (linux distro) with php (widthout using linux commands)?

edit: sorry, the objective is to be aware of the ram available in the server / virtual machine, for the particular server (even if that memory is shared).

Linux commands can be run using the exec function in PHP. This is efficient and will do the job(if objective is to get the memory).

Try the following code:

<?php
  exec("free -mtl", $output);
  print_r($output);
?>

Small and tidy function to get all of its values associated to their keys.

$contents = file_get_contents('/proc/meminfo');
preg_match_all('/(\w+):\s+(\d+)\s/', $contents, $matches);
$info = array_combine($matches[1], $matches[2]);

// $info['MemTotal'] = "2047442"

exec("grep MemTotal /proc/meminfo", $aryMem); $aryMem[0] has your total ram minus kernel usage.
